Since we are always calling `m_entries[key]` anyway, this code could be a bit
simpler:
```
Entry &entry = m_entries[key];
if (entry.refcount == 0) {
// This is a new progress event.
entry.data = progress_data;
entry.refcount = 1;
return;
}
// This is an existing progress event.
```
I assume that accessing a non existent key in the string map will return an
default constructed object right?
